Patented Jan. 3, l 967 3,295,695 ARRANGEMENT N SHELVES, PREFERABLY FOR BOOK-(JASES Helge Carmstrom, 79 Pack, Virserum, Sweden Filed Mar. 24, 1965, Ser. No. 537,130 Claims. (Cl. 211148) The present invention relates to an arrangement on shelves, preferably for bookcases, where the shelf has, in both its transverse ends, a groove parallel to the support surface of the shelf, said groove extending from the rear edge of the shelf along the transverse end to a short distance from the forward edge of the shelf, and in which a double-shanked shelf support means is introduced into said groove for the support of the shelf, said support means with its shanks being secured in holes contained in the side walls of the book-case, said holes being arranged in pairs in the horizontal plane, so that by the removal of the shelf support means to another pair of holes the shelves become adjustable.

Shelves of the above described type have been known and used since long, the shelves having been fitted horizontally. During recent years, however, it has become the trend to have an inclined shelf in book-cases for periodicals and the like, such a shelf being provided at its lower part with a rail, against which the periodicals rest. Heretofore, it has not been possible, with the known shelf support means, to arrange an inclined shelf. This problem, however, has been solved in a simple way by the present invention.

The invention is characterized substantially in that the part of the groove which is situated nearest to the supporting surface of the shelf, is provided with a shoulder for the shelf support means at the rear edge of the shelf.

One embodiment of the invention will be described in conjunction with the appended drawing, in which FIG. 1 shows, in a side elevation, a shelf for periodicals, said shelf being fitted according to the invention, FIG. 2 shows in a plan view the known, double-shanked shelf support means inserted in a book-case wall together with a section of a shelf.

In FIG. 1 the shelf 1 is shown with a rail 2 transverse to the shelf, said rail being intended for retaining periodicals. In the ends of the shelf, a groove 3 has been cut, and this groove 3 is open at the rear edge 4 of the shelf 1 and extends along the end of the shelf 1 to terminate at a distance from the forward edge 5 of the shelf 1. The entrance 6 to the groove 3 has the width required to allow a double-shanked shelf support means 7 to be inserted into the groove 3.

The shelf support means 7 is previously known and is of that type, which with its shanks is inserted into holes 9 arranged in pairs in the inner walls ltl of the book-case. On the removal of a shelf from one level to another in a book-case, the shelf is drawn out in a forward direction so that the shelf support means are freed, allowing them to be removed to a new position in the book-case, the shelf subsequently again being disposed in conjunction with the shelf support means. In order that a shelf may be used as a periodical shelf and thereby be inclined in the requisite way, the shelf support means are made longer so that the distance between their shanks corresponds to the distance betwen a hole on one level and another hole on another level in the bookcase wall, as is apparent from FIG. 1, where it also is shown how an ordinary, horizontal shelf is arranged by a known method.

To enable the shelf 1 to be retained according to the invention, the groove 3 is provided with a shoulder 8 at the rear edge 4 of the shelf.

In the illustrated embodiment this shoulder 8 is formed, in that a section of the groove 3 has been increased in width to a distance from the rear edge 4 of the shelf. When a shelf for periodicals is to be fitted into a bookcase, two shelf support means are first secured at the desired level, the shelf being subsequently slid onto the shelf support means. When the fitting has been completed, the shelf support means shank situated nearest the rear edge of the shelf will be positioned in the widened area of the groove, and through weight of the shelf the shank will bear against the shoulder as illustrated in FIG. 1, which results in a secure retaining of the shelf. When such a shelf shall be removed, the rear edge of said shelf is first raised so that the shelf support means shank is positioned oppositely the entrance 6 of the groove, whereafter the periodical shelf can he slid out in the usual manner.

The invention can, of course, be varied in many ways within the scope of the inventive idea. In the embodiment illustrated, the groove 3, in its widened section, has been cut with an even width.

The groove 3 can, however, be cut so that its width decreases continuously in the direction of the forward edge of the shelf, in order that the groove, nearest to the forward edge of the shelf, has a width corresponding to the entrance 6 of the groove 3 i.e. corresponding to the thickness of the shank of the shelf support means. The groove can also be cut with a width, along its entire length, corresponding to the maximum width in FIG. 1, in such a manner, that a plate is secured at the entrance 6 of the groove 3, which plate forms the shoulder 8.

What I claim is:

1. An arrangement on shelves, preferably for bookcases, whereat the shelf at its two transverse ends is provided with a groove parallel to the support surface of the shelf, said groove extending from the rear edge of the shelf along the transversal end and forward to a short distance from the forward edge of the shelf, whereat a double-shanked shelf support means is introduced into the groove for the support of the shelf, said support means with its shanks being secured in holes contained in the end walls of the book-case, said holes being arranged in pairs in the horizontal plane so that the shelves are adjustable by the removal of the shelf support means to another pair of holes, in which arrangement that part of the groove which is situated nearest the support surface of the shelf is provided with a shoulder for the shelf support means at the rear edge of the shelf.

2. An arrangement according to claim 1, wherein a section of the groove is widened at a distance from the rear edge of the shelf to form the shoulder.

3. An arrangement according to claim 1, wherein a plate is secured at the entrance of the groove, thereby covering a part of the opening of the same and forming the shoulder.

4. An arrangement according to claim 2, wherein the widened section of the groove is of an even width along its entire length.

5. An arrangement according to claim 2, wherein the width of the groove decreases continuously from the 3 4 shoulder in a direction towards the end of the groove, 2,877,519 3/1959 Propst 211148 X located at the forward edge of the shelf, to the width 3,030,162 4/1962 Brooks 211134 X required for the shelf support means. 3,039,621 6/ 1962 Pilcher 108107 3,114,460 12/1963 Abrarnowski 108-107 X References Clted by the Exammer 3,186,363 6/1965 MOOre 211 148 X UNITED STATES PATENTS 3,186,527 6/1965 Konstant et a1. 211 -148 11 1915 vogel 211 134 3,223,246 12/1965 Daitch 211134 929 Kuck 211 135 X 3,243,047 3/1966 Witteborg 21188 gig ,fig; 10 FRANK B.
